Dietary Exposure Evaluation Model DEEM

In the eighties and early nineties, the USEPA evaluated dietary risk with an analysis method known as the Dietary Risk Evaluation System (DRES) (USEPA, 1991), which was based on the USDA s 1977 to 1978 National Food Consumption Survey. Consequently, dietary exposure assessments became genetically referred to as DRES analyses. Currently, the USEPA is using the Dietary Exposure Evaluation Model (DEEM , Version 7.87) (Exponent, 2000), which allows exposure to be calculated from 1994 to 1996 CSFII along with the 1998 supplemental children s survey information.

One difference between the US and the EU approach to probabilistic dietary risk assessment is in the method of sampling. In the US approach, probabilistic sampling is done for the residue distribution. However, Exponent s Dietary Exposure Evaluation Model (DEEM [10]) currently used by the EPA for dietary risk assessment uses all of the food consumption data. In the EU, it appears that probability sampling may be performed from both the residue and consumption distributions [11], In the US, the CARES... 

Ingestion exposures can be estimated using the Dietary Exposure Evaluation Model (DEEM), a computer-based model developed by Novigen Sciences, Inc. to estimate dietary intake of chemical residues (California Environmental Protection Agency 2007). The outputs from this model include estimates of dietary exposure over multiple averaging times so that both acute and chronic exposures can be considered. Exposures can also be considered on a population or individual level. The...
